69920603 ÷ 452 
Our goal is to divide 69920603 by 452.

Moving on to step 1:
452 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 452

Moving on to step 2:
69 divided by 452 is 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 452

Advancing to step 3:
When dividing 699 by 452, we get 1 with a remainder of 247.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 247 after subtracting 452 from 699.
Take the next digit (2) from the dividend and append it to 247, then repeat: 2472 / 452

Let's proceed to step 4:
When dividing 2472 by 452, we get 5 with a remainder of 212.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2260 away from 2472, we end up with 212.
Take the next digit (0) from the dividend and append it to 212, then repeat: 2120 / 452

Advancing to step 5:
452 can be fit into 2120 4 times, resulting in a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtracting 1808 from 2120 leaves us with 312.
Bring next digit (6) of the dividend behind the 312 and repeat the process: 3126 / 452

Step 6:
3126 divided by 452 is 6 with a remainder of 414.
Write down 6 as next digit of the result. 
Result so far: 1546.0
The remainder is 414 after subtracting 2712 from 3126.
Grab the next digit (0) from the dividend, add it to 414, then carry on: 4140 / 452

On to step 7:
4140 divided by 452 is 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 15469.0
Subtracting 4068 from 4140 leaves us with 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 452

Step 8:
452 goes into 723 1 times with a remainder of 271.
The next digit of our result is 1. 
Result so far: 154691.0
Subtract 452 from 723 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 9:
452 goes into 2710 5 times with a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 154691.5
If we take 2260 away from 2710, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
If we divide 4500 by 452, we get 9 and a remainder of 432.
Write down 9 as next digit of the result. 
Result so far: 154691.59
Subtract 4068 from 4500 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 11:
The number 452 fits into 4320 9 times, leaving a remainder of 252.
The next digit of our result is 9. 
Result so far: 154691.599
The remainder is 252 after subtracting 4068 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 154691.599 with a remainder of 0.0252.
